PITTSBURGH, Pennsylvania (CNN) - Hillary Clinton used her trademark laugh Thursday to deflect a question about the $800,000 her husband earned in 2005 giving speeches for a Bogota-based group that supports the Colombia free trade agreement - the same trade deal she currently opposes.

Asked by CNN if those earnings represented a conflict of interest given that she has dipped into her family's pocketbook to pay campaign bills, Clinton threw up her hands and laughed loudly for several seconds.
